The logback logger implementation is a super quality implementation. If you intend to write serious code that go into production, you may want to evaluate this option..
package com.javavillage.slf4j; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class SLF4JSample { private static Logger LOGGER = LoggerFactory.getLogger(SLF4JSample.class); public static void main(String[] args) { LOGGER.info("Hi, Welcome to SLF4J exmaple"); } }for now I am adding below dependency for maven pom.xml
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.13</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.0.13</version> </dependency>logback.xml
<configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <logger name="javavillage" level="DEBUG"/> <root level="INFO"> <appender-ref ref="STDOUT" /> </root> </configuration>project structure after maven build.
Now you see logging output on STDOUT with INFO level..
